React PixiJS

CircleCI

Write PixiJS applications using React declarative style.

Install

yarn add @inlet/react-pixi

or

npm install @inlet/react-pixi --save

Usage

With ReactDOM

import { Stage, Sprite } from '@inlet/react-pixi'

const App = () => (
  <Stage>
    <Sprite image="./bunny.png" x={100} y={100} />
  </Stage>
)

This example will render a PIXI.Sprite object into a Root Container of a PIXI.Application on the page. The Stage object will create a valid <canvas /> element to render to.

Without ReactDOM

import { render, Text } from '@inlet/react-pixi'
import * as PIXI from 'pixi.js'

// Setup PIXI app
const app = new PIXI.Application(800, 600, {
  backgroundColor: 0x10bb99,
  view: document.getElementById('container')
})

// Use the custom renderer to render a valid PIXI object into a PIXI container.
render(<Text text="Hello World" x={200} y={200} />, app.stage)

Examples

Watch the collection on codepen.

Custom Components

Currently the following Components are implemented by default:

You can easily add new components to your project:

./components/Rectangle.js

import * as PIXI from 'pixi.js'
import { PixiComponent } from '@inlet/react-pixi'

export default PixiComponent('Rectangle', {
  create: props => {
    return new PIXI.Graphics()
  },
  didMount: (instance, parent) => {
    // apply custom logic on mount
  },
  willUnmount: (instance, parent) => {
    // clean up before removal
  },
  applyProps: (instance, oldProps, newProps) => {
    const { fill, x, y, width, height } = newProps
    instance.clear()
    instance.beginFill(fill)
    instance.drawRect(x, y, width, height)
    instance.endFill()
  }
})

App.js

import { Stage } from '@inlet/react-pixi'
import Rectangle from './components/Rectangle'
export default () => (
  <Stage>
    <Rectangle x={100} 
               y={100} 
               width={500} 
               heigth={300} 
               fill={0xff0000} />
  </Stage>
)

Access the PIXI.Application in child components

Consider this rotating bunny example:

./components/RotatingBunny.js

import { Sprite } from '@inlet/react-pixi'

class RotatingBunny extends React.Component {

  state = { rotation: 0 }

  componentDidMount() {
    this.props.app.ticker.add(this.tick)
  }
  
  componentWillUnmount() {
    this.props.app.ticker.remove(this.tick)
  }
  
  tick = (delta) => {
      this.setState(({ rotation }) => ({
          rotation: rotation + 0.1 * delta
      }))
  };
  
  render() {
    return <Sprite image="./bunny.png" rotation={this.state.rotation} />
  }
}

There are 2 ways of accessing the PIXI.Application instance.

  1. Using AppConsumer and pass the instance via render props:

App.js

import { Stage, Container, AppConsumer } from '@inlet/react-pixi'
import { RotatingBunny } from './components/RotatingBunny'

export default () => (
  <Stage>
    <Container>
      <AppConsumer>
        {app => <RotatingBunny app={app} />}
      </AppConsumer>
    </Container>
  </Stage>
)
  1. Or use a Higher Order Component:

App.js

import { Stage, Container, withPixiApp } from '@inlet/react-pixi'
import { RotatingBunny } from './components/RotatingBunny'

const BunnyWithApp = withPixiApp(RotatingBunny)

export default () => (
  <Stage>
    <Container>
      <BunnyWithApp />
    </Container>
  </Stage>
)

API

<Stage />

Renders Root Container of a PIXI.Application.

Props:

  • width the width of the renderers view, default 800
  • height the height of the renderers view, default 600
  • onMount a callback function for the created app instance
  • onUnMount a callback function when the Stage gets unmounted
  • raf use the internal PIXI ticker (requestAnimationFrame), default true
  • renderOnComponentChange render stage on Stage changes? only useful in combination with raf
  • options see PIXI.Application options

The Stage stores the created PIXI.Application instance to context, which can be accessed using a Provider or a Higher Order Component.

Components

Pass component options as props, example:

import { Sprite } from '@inlet/pixi-react'

const MyComponent = () => (
  <Sprite image=".image.png" x={100} y={200} />
)

The image prop here is a short-hand for PIXI.Sprite.fromImage():

import { Sprite } from '@inlet/pixi-react'

const texture = new PIXI.Sprite.fromImage('./image.png')

const MyComponent = () => (
  <Sprite texture={texture} x={100} y={200} />
)
